What to know before buying

Listing details to confirm

The listing identifies the material as Leather, while the feature description calls the outer shell stretch poly fleece and the palm microfiber leather. It also uses the spelling “Thinsultate” in the insulation claim, while elsewhere naming 3M Thinsulate. Treat the material and insulation wording as inconsistent listing details, not confirmed construction specifications.

Customer feedback highlights reported warmth in freezing conditions, comfort, durability and usefulness for ice fishing. Buyers may value the convertible design for switching between warmth and finger access, but feedback is mixed on the magnets, with some reports that the thumb flap does not stay in place. That concern matters when relying on the listing’s magnetic flap design during tasks requiring exposed fingers.

Mixed feedback

Feedback on the magnetic fit is mixed. Some find the magnets convenient, while others report that the thumb flap does not stay in place.

Yes. The listing says the finger and thumb flaps can be moved aside, with magnets intended to hold them out of the way.
